Bluetooth is an open specification for wireless data transmission that operates on the globally available 2.4GHz radio frequency. Bluetooth devices can communicate with each other within a 30-foot range.

Apple has also posted Bluetooth Preview 2.1 for Mac OS X , the newest version of its software that enables wireless data transfers to Bluetooth devices. Macintosh users will be able to use a Bluetooth enabled mobile phone for Internet connection, perform a HotSync operation with a Palm handheld device, and exchange files between two Bluetooth enabled computers.
